Have you checked the spring on your garage door?
Eventually, all springs will wear out and break, even high quality steel springs like the ones used by Clopay. If you have an older garage door, have a garage door installation professional inspect and replace the springs if necessary. If your garage door has two springs, replace both at the same time, even if one is not broken. This will prevent any damage caused if the second spring breaks, and also keep your door working efficiently.
